XmlSchemaSequence Class
Represents the sequence element (compositor) from the XML Schema as specified by the World Wide Web Consortium (W3C). The sequence requires the elements in the group to appear in the specified sequence within the containing element.
Assembly: System.Xml (in System.Xml.dll)
System.Xml.Schema::XmlSchemaObject
System.Xml.Schema::XmlSchemaAnnotated
System.Xml.Schema::XmlSchemaParticle
System.Xml.Schema::XmlSchemaGroupBase
System.Xml.Schema::XmlSchemaSequence

|---|---|---|
![]() | Equals(Object^) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | MemberwiseClone() | |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
The following example shows the XmlSchemaSequence class.

The following XML file is used for the preceding code example.
<?xml version="1.0" encoding="IBM437"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="thing1" type="xs:string"/> <xs:element name="thing2" type="xs:string"/> <xs:element name="thing3" type="xs:string"/> <xs:attribute name="myAttribute" type="xs:decimal"/> <xs:group name="myGroupOfThings"> <xs:sequence> <xs:element ref="thing1"/> <xs:element ref="thing2"/> <xs:element ref="thing3"/> </xs:sequence> </xs:group> <xs:complexType name="myComplexType"> <xs:group ref="myGroupOfThings"/> <xs:attribute ref="myAttribute"/> </xs:complexType> </xs:schema>
